It's so nice to see colors in any kind of government, industrial, or commercial building. The "everything must be gray/beige" fad has dominated institutional interior design for at least 30 years. Maybe it's just nostalgia, I remember the wall colors in banks, schools, doctor's offices, mcdonalds, and so on in the 1970s and they seemed so wonderful. All these things got a coat of white paint sometime in the 2000s and look the same as everywhere else now.
I feel that too. My house had significant chunks painted a vivid aquamarine when I moved in 2018, and my now-ex insisted that we paint over it all in grey.
After she moved out, I put up greens, yellows, brown, and blue all over the house. It's not quite as "public pool" feeling as that original aquamarine, but it's certainly more lively than grey/white. Funny enough though, when I had a designer come in to take measurements and do a mockup for a kitchen reno... everything was back to white because that's step one in making it look "modern" even though part of the pitch is custom cabinetry that won't just look like that same white IKEA stuff that everyone installs now.
It's common for homes especially when prepped for sale because neutral colors won't clash with whatever the potential buyer might want to bring in e.g. furniture, artwork, or other decor.
Most of the rooms in my house are painted in colors and I mostly like it but it can sometimeds feel fatiguing. I've thought about repainting in a neutral gray or green.
Install the boring shit and use colored vinal wrap for fun. Good resale value and you can enjoy life.
I had to get my whole house repainted after a kitchen fire. Have some black and a lot of white (trim and ceilings) but also subtle green in upstairs rooms and very subtle orange everywhere else. Kept it simple but prefer it to everything being a light gray like a relative has. There still aren’t that many different paints if retouching is ever needed.
